• How does AC work?
Juli2301 [7.4K]
AC reverses the current in periods, and the current flows in 2 directions. 
DC only flows in one direction and is constant. 

AC is typically used to transfer power over long distances from a generator to your home, stepping it up after it's generated to send it over the distance, then stepping it back down so that it is usable in your home.

DC is used typically inside of devices, as it sends a certain amount of electricity through the wires.

Nicolas Tesla, was ripped off by Edison to replace his DC stations with AC instead. ^^

An ant climbs at a steady speed up the side of its
lianna [129]

The weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.

<u>Given the following data:</u>

  • Angle of inclination = 30.0°.

<h3>What is a free-body diagram?</h3>

In Science, a free-body diagram can be defined as a graphical illustration which is typically used to visualize moments, tension, and applied forces that are acting on an isolated or rigid body (object) while using arrows pointing in the direction of these forces.

In this scenario, the weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.

A solid uniform sphere of mass 5 kg and radius 0.1 m rolls down an inclined plane without slipping. if the sphere's center of ma
ANTONII [103]

Since sphere is performing pure rolling motion

So here the contact point of sphere with respect to inclined plane is always at rest.

This contact point will not move at any instant and and hence sphere will perform pure rolling.

So here we can say that sphere will have some friction force at the contact point but there is no displacement of that point.

So the work done by this static friction will always ZERO.

W_{friction} = F.d

W_{friction} = 0

So there is no work done by friction on the sphere while it is in pure rolling.

Burka [1]
The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as sun's rays hit them directly.
Therefore, the answer is C.
